We apologize for Proteopedia being slow to respond. For the past two years, a new implementation of Proteopedia has been being built. Soon, it will replace this 18-year old system. All existing content will be moved to the new system at a date that will be announced here.

[[http://www.uniprot.org/uniprot/CP19A_HUMAN CP19A_HUMAN]] Defects in CYP19A1 are a cause of aromatase excess syndrome (AEXS) [MIM:[http://omim.org/entry/139300 139300]]; also known as familial gynecomastia. AEXS is characterized by an estrogen excess due to an increased aromatase activity. Defects in CYP19A1 are the cause of aromatase deficiency (AROD) [MIM:[http://omim.org/entry/613546 613546]]. AROD is a rare disease in which fetal androgens are not converted into estrogens due to placental aromatase deficiency. Thus, pregnant women exhibit a hirsutism, which spontaneously resolves after post-partum. At birth, female babies present with pseudohermaphroditism due to virilization of extern genital organs. In adult females, manifestations include delay of puberty, breast hypoplasia and primary amenorrhoea with multicystic ovaries.<ref>PMID:8265607</ref><ref>PMID:8530621</ref><ref>PMID:9211678</ref>
